Yeah - I'll be in that :)

Yeah thats a nice chip, there's also the PIC ones and an ACE which is
about the size of a matchhead, someone made a web server in one !
Trouble is it doesn't have SPI :( Would be great if it had an
uncommitted shift register in the structure... <sigh> There's
also the at89c2051 which is a bit bigger but has serial and will run
to about 30MHz - someone has reliably run these at 50MHz ! Not bad for
a $5 cpu <phew>

In regards to software - mmmm

What would be real useful and interesting is being able to do the low end
comms stuff for W95/98 with higher end user interface etc

ie A windows based comm driver which is configurable for almost anyone's
(published) EFI controller. ie Look up table of comms requirements for
a particular EFI controller, also look up a windows bitmap resource for
the menus, mimic display etc etc

Actually could be worthwhile as a commercial product,
(Want me to get a government grant for that - hint ;-)

I'm probably a bit like Bernd in that I have lots of low end micro experience,
some high level stuff but have little experience (or interest for that matter)
with the vagaries (and there are lots) of Windows API calls such as:-

a.	Virtual device drivers
b.	Handling Menu variations
c.	Handling Resource/bitmap variations
d.	Scheduling these into a pre-emptive o/s
	(Stuff I did with win 3.11 was ok but want to move up)

Any comments on this 'higher end' display/user access side ?
